摘要： Systems and methods for remote endarterectomy are disclosed. In an embodiment, a device for remote endarterectomy includes an elongated member, having a proximal end, a distal end, and a longitudinal axis therebetween; an endarterectomy unit at the distal end of the elongated member formed by a first member engaged to a second member in a substantial secure alignment with the second member, wherein the endarterectomy unit has a circumferential enclosure configured to separate a plaque core from a blood vessel and an open region surrounded by the enclosure and configured to receive the separated plaque core therethrough; and an actuator coupled to the proximal end of the elongated member for translating the first member relative to the second member across the open space to transect the plaque core received in the open space.

摘要： Non-occlusive modeling catheters including a dilation device for expanding an endoprosthesis implanted in a vessel are disclosed. In an embodiment, a modeling catheter includes a device comprising a plurality of compliant wires braided in a double overlapping pattern and having a length spanning between a proximal end of the device and a distal end of the device, wherein the device is positioned in at least a portion of an endoprosthesis implanted in a vessel, wherein, when the device is in a relaxed state, a plurality of spaces are formed between the plurality of wires to allow fluid to move freely through the plurality of spaces, and wherein, when the device is in a dilated state, the plurality of wires are sufficiently designed to exert a radial force on the endoprosthesis while continually allowing the fluid to move freely through the plurality of spaces.

摘要： A shunt includes a first occlusion assembly and a second occlusion assembly. The first occlusion assembly includes a first occlusion fluid conduit that carries an inflation fluid from a fluid source to a first balloon of the shunt. The second occlusion assembly includes a second occlusion fluid conduit that carries an inflation fluid from a fluid source to a second balloon of the shunt. The first occlusion assembly includes a first color and the second fluid assembly includes a second color, distinct from the first color. The distinctive colorings of the first and second occlusion fluid conduits remain visible within an operative field during an endarterectomy procedure and allow a user to distinguish the first occlusion assembly from the second occlusion assembly during the procedure.
